It is a fatal disease, similar to scrapie in sheep and goats, caused by a prion.A major epizootic affected the UK, and to a lesser extent a number of other countries, between 1986 and the 2000s, infecting more than 190,000 animals, not counting those that remained undiagnosed.
Both livestock and companion animals are susceptible to mite infestation and although this article will focus on livestock, the two are similar. Humans also may become infested by contagion from these domestic animals (a zoonosis). Infestation by mites usually causes skin diseases known as mange, scab, demodecosis, or in general as acariasis ...
